SPECIFICATION forming part of Letters Patent No; 755,047, dated March 22, 1904. Application ned Mar'ch 17, 1902l serial N6. 98,551. (No model.)

T0 a/ZZ whom t may concern: i

Be it known that I, ALEXANDER ROTH ROB- ER'rsoN, a citizen of the United States, and a resident of Pass Christian, in the county of Harrison and State of. Mississippi, have invented a new and Improved Bottle-Seal, of which the following is a full, clear, and exact description. p

This invention relates to a device adapted to secure frangible caps over the mouths of bottles.

A purpose for which the invention is particularly intended is that of preventing tampering with the contents of a bottle.

To this end the device embodies the combination, with the neck of a bottle which is adapted to receive a cork in the usual manner and which is formed with two annular beads onits outer surface, of a frangible cap, preferably of glass, and a corrugated locking-spring adapted to lie between the beads on the neck of the bottle and within the cap, so as to coact therewith in a peculiar manner, thus holding the cap in place. Vhen once seated, the cap can only be removed by breaking it away,

and in practice I purpose forming the cap with an annular weakened portion, which'will facilitate its fracture.

This specification is an exact description of one form of the invention, while the claims' define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specication,

in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a vertical section of the invention. Fig. 2 is a horizontal section onthe line 2 2 of Fig. 1. Fig. 3 is a perspective view of the corrugated locking-spring, and Fig. 4: is a perspective view of the cap.v

c indicates theneck of a bottle, the usual top bead a' whereof is squared slightly effectively to work with the locking-spring, as will be hereinafter brought out. Below the bead c the neck is formed with a second bead c2, both of the beads being exterior and being distanced apart suiiiciently to receive the locking-spring.

indicates the cap, which has an internal shoulder 6' formed at its lower portion, and

below this shoulder the cap has a contracted part b2, adapted to lie snugly over the bead a2.

Z13 indicates the annular weakened part of the cap, which facilitates the fracture of the cap by allowing the top thereof to be removed. The spring cis formed of a strip of spring metal, corrugated as shown, and is adapted to be given annular form, so as to lie around the neck of the bottle between the beads a and a2. The upper edge of this spring-strip at the outer corners of the corrugations is cut away or beveled, as indicated at c', to facilitate placing the cap in position.

In using the invention after the bottle is properly corked the springcatch is placed around the neck of the bottle between the beads d and a2 with the beveled part c of the catch upward. The ca p is now forced downward over the mouth of the bottle, the contracted portion b2 of the cap riding over the inclined part or beveled edges c of the springcatch and compressing the catch suiiiciently to allow the contracted portion of the cap to pass over the catch and down on the bead a2. As soon as the contracted portion b2 of the cap passes the spring-catch the catch distends and engages the internal shoulder of the cap.

This locks the cap securely in place and renwithout departing from the spirit and scopey of my invention as dened in the claims.

Having thus described my invention,I claim as new and desire to secure by Letters Patent- 1. The combination with a bottle having the neck thereof formed with exterior annular flanges or beads spaced from each other, of a spring-catch formed of a strip of sheet metal corrugated transversely and bent into annular form to lie between said beads, the

IOO

upper edge of said strip at the outer corners of the corrugations being eut away or beveled for the purpose specified, and a cap adapted to fit over the beads on the neck of the bottle and to receive the spring-catch, said cap having an internal shoulder adapted to engage the lower edge of the spring-catch, to hold the cap in place.

2. 1n a bottle-seal, the combination with the neck of the bottle and with the sealing-cap I being cut away or beveled to facilitate placing the cap in position.

1n testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
